IMO A.563 Flammability

The IMO A.563 certification is the International Maritime Organization’s criteria for the flame resistance of vertically supported textiles and films, including curtains, draperies, and other free-hanging fabric that have qualities of fire resistance equal to or better than those of wool with a mass of 0.8kg/m2. This certification can also be done via IMO A.471, however IMO A.563 specifies criteria for ships sailing in international waters.
